Question

how many metres of carpet 63cm wide will be needed to cover the floor of a room 14m by 9m?

Answer 1

length of carpet required = 1400cm×900cm/63cm = 20000cm = 200m

Answer 2

Answer:

Step-by-step explanation:

Dimensions of a carpet :

Width(w) = 63 cm = 0.63 m

Let length = l cm

Dimensions of the floor:

Length (L) = 14 m,

Breadth (B) = 9 m,

Now,

area of the carpet = area of the floor

=> l × w = L × B

=> l × 0.63 m = 12m × 9m
